Arpit Agnihotri 2 years, 8 months ago (10214610)

46%(w/w) C2H5OH = 46 gram of C2H5OH (solute) present in 100 gram of solution(solvent:water) mole fraction = (mole of solute)/ (mole of solute + mole of solvent) so, mole fraction of C2H5OH = [46/(2*12+6*1+1*16]/[{46/(2*12+6*1+1*16}+{54/2*1+1*16}] = [46/46]/[{46/46}+{54/18}] = 1/[1+3] = 1/4 hence, ans : mole fraction of C2H5OH = (1/4) molar mass of: C - 12; H - 1; O - 16 mole = mass / molar mass

Arpit Agnihotri 2 years, 8 months ago (10214610)

total weight of solution(NaOH+H20) = 40+54 = 94 mole = mass/molar mass the molar mass of Na =40; O =16;H=1 mole fraction = mole of substance to be founded/mole fraction of solution now, mole fraction of NaOH = moles of NaOH/ (Mole of NaOH+Mole of H2O) = (40/40)/[(40/40)+(54/1*2+16*1)] = 1/[1+3] = 1/4 so, mole fraction of NaOH in the solution = 1/4 mole fraction ( solute+solvent) = 1 therefore mole fraction of H2O = 1-(1/4) mole fraction of H2O=3/4
